About this study

Official title: An Assessment of the Biological and Clinical Effects of Palbociclib (PD 0332991) With Ovarian Suppression and Letrozole in the Neoadjuvant Treatment of Patients With Premenopausal Estrogen-Receptor Positive/HER2-Negative Primary Breast Cancer

This study will look at the safety and effectiveness of the combination of palbociclib and letrozole and ovarian suppression for premenopausal patients who have ER-positive/HER2-negative breast cancer that has not yet been treated.

Read the detailed description

NSABP FB-13 is a phase II, open label study to examine the biological and clinical effect of neoadjuvant endocrine therapy with letrozole, palbociclib and ovarian suppression in premenopausal patients with estrogen-receptor (ER) positive, HER2-negative, early invasive breast cancer.

Premenopausal women newly diagnosed with ER-positive/HER2-negative early breast cancer who are suitable candidates for neoadjuvant endocrine therapy will be invited to join the FB-13 trial. A screening Oncotype DX Breast Recurrence Score® will be performed by Genomic Health, Inc. (GHI) on the diagnostic tissue of consenting patients to verify eligibility.

Patients will be stratified into one of two approximately equal sized cohorts based on baseline Breast Recurrence Score (RS) (cohort 1: patients with RS less than 11 or cohort 2: patients with RS 11 to less than 26).

Patients in both cohorts will receive letrozole 2.5 mg by mouth daily, palbociclib 125 mg by mouth daily for 21 days of a 28 day cycle, and goserelin 3.6 mg subcutaneous injection on Day 1 of each 28 day cycle. At Week 6 of study therapy, patients will have two core-cut biopsies. Patients from both cohorts who have a Ki67 less than 10% level will continue receiving study therapy for a total of 6 cycles. Patients with a persistent Ki67 greater than or equal to 10% at week 6 will permanently discontinue study therapy and begin neoadjuvant chemotherapy or proceed to surgery at the discretion of the treating physician.

Pre-treatment samples and post-surgical samples will be collected and analysed to identify subgroups of patients who may derive the most clinical benefit. The results of the biological analyses may allow a target sensitive population to be selected for future trials. The tissue collected in FB-13 will form an integral part of the primary analyses; so all core biopsies in this trial will be mandated for patients.

Two core-cut biopsies will be collected from each patient at baseline, after 6 weeks of study therapy, and upon completion of study therapy (24 weeks) at the time of definitive surgery.

Blood samples will be collected at baseline, 4 weeks, and at 24 weeks for estrone and estradiol levels to demonstrate ovarian suppression. A 4-week estradiol level in the postmenopausal range will be required to receive further treatment on study.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Letrozole, Palbociclib and Goserelin in people with Breast Cancer, run by NSABP Foundation Inc at 15 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 17 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Complete Cell cycle arrest (time frame: From study entry to the time of the 6 week tumor biopsy to assess Ki67, approximately 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2022.
